Abstract
A silicon-based photonic chip is provided that includes an interface for optically coupling the photonic chip to an optical fiber or an optical fiber assembly. The interface includes: a single-mode waveguide configured to guide light and to provide a first light beam; a first optical element configured to expand the light beam in a first direction in-plane of the photonic chip, thereby providing an expanded light beam; and a second optical element configured to deflect and to further expand the expanded light beam in a second direction, thereby providing an output light beam from the photonic chip. Also provided are methods for fabricating such a photonic chip.
